浓差极化视角下的离子渗透能量转换实验研究

Ionic osmotic energy conversion is a renewable energy technology directly converting osmotic salinity gradient energy into electrical energy. However, the ion concentration polarization (ICP) effect limits ion migration near nanochannels and electrodes, resulting in low ionic osmotic energy conversion performance. This paper proposes a mechanism to weaken the ion concentration polarization effect through three regulation methods: temperature, speed, and stirring. By establishing corresponding ionic osmotic energy conversion experimental systems, the impact of the above regulation methods on the power density and energy conversion efficiency is clarified. The results contribute to understanding the ion concentration polarization mechanism in the field of osmotic energy conversion and provide guidance for improving the performance of ionic osmotic power generation.
